Came across this article and found it interesting. Especially the part of the reason for oil-consumption in the VQ engines. First I've heard of this, has anyone else seen this as being a possible reason for oil consumption?

The Nissan VQ37VHR is reliable and durable, but sometimes the following problems can happen:

• High oil consumption. The VQ37VHR has a catalytic converter and it is very sensitive to the fuel quality. They produce ceramic dust, which damaging the cylinders sleeve and piston rings. As a result, the engine has low compression, high fuel, and oil consumption. Such an engine requires repair or replacement.
  To prevent this problem, you need to change the upper catalytic converters for high flow catalytic converter. It will decrease the ecological standard, but this problem will not happen.

 

That web site is trash... so much wrong information.

 

such as? …

 

I'll let you figure that out...

 

I have been around this platform for a decade now and have never heard about this potential cat leading to piston ring degradation issue. It would be good to know the source; A Blackstone oil analysis would likely reveal if there is excessive "ceramic dust" inside the motor.

The overheating comment is also unwarranted as most of the overheating problems we see here on the forum are linked to the plastic heater hose connector, extreme neglect of the upper and lower radiator hoses, and an overall lack of understanding regarding the patience needed to bleed the air out of the system properly. Oil and trannie fluid runs warm, but unless you are pushing the car pretty hard or extending the service intervals for each based on an internet recommendation, I doubt you will ever notice.

I've seen much of the spec data posted within varous Wikis and Youtube videos that discuss the VQ37VHR. Looks like this guy mines data for alot of platforms, so I think the intent is genuine.
